    Transpiration

    • Describe any experimental controls used in the investigation.
    • What environmental factors that you tested increased rate of transpiration? Was the rate of transpiration increased for all plants tested?
    • Did any of the environmental factors (heat, light, or wind) increase the transpiration rate more than the others? Why?

    Stem Cross Sections

    • Which plants were used to represent monocot and dicot.
    • Name and describe the 3 tissue types that run continuously through the plant from roots to shoots.
    • What is the major difference between the vascular arrangement in the monocot vs. the dicot cross section.
